I’m using UE in a pipeline to train neural networks. Cuda is slowed down by ~20% when the editor is open but doing nothing with no viewports and no panels. Only thing that works is completely blocking the process. I disabled realtime and thumbnail generation. Are there any settings besides ‘Use less CPU when in Background’ I didn’t think of? Any hints would be appreciated.
This seems to be a bug in 5.1 as there is no GPU usage in 5.0. Unfortunately, the relevant assets didn’t downgrade to 5.0
Are you using the ui inside the editor to drive the neural net in some way?
If you just need to run the project then perhaps you could try running 5.1 in headerless mode.

-RenderOffscreen doesn’t eat the GPU and is a much cleaner solution for me anyways. Thank you!
